For the multivariate normally distributed data with the dimension larger than or equal to the number of observations,<br>or the sample size, called high-dimensional normal data, we proposed a test for testing the null hypothesis that the covariance<br>matrix of a normal population is proportional to a given matrix on some conditions when the dimension goes to infinity.<br>We showed that this test statistic is consistent. The asymptotic null and non-null distribution of the test statistic is also<br>given. The performance of the proposed test is evaluated via simulation study and its application.
